Application filed December 1, 1922. Serial No. 604,379.

To aZZ whom it may concern:

Be it known that I, VINCENT J. WHITNEY, a citizen of the United States, and a resident of San Francisco, in the county of San' Francisco and State of California, have invented a certain new and.v useful Improvement in Vindow Supports, of which the following is a specification.

This invention relates to means for supporting a window in such a manner that it may be swung open and free from theicasing 'at both sides whereby it may be cleaned onv the outside without the necessity of approaching it from the exterior of the buildit is the object of my invention to provide a device of the character indicated that.

will be smooth and positive in its operation, and wherein a simple and highly efficient means is provided for securing the parts ofthe device against movement when extended. It is a further object of my invention to provide a device of the characterv indicated that will be simple in operation, economical window holding shoe.

Referring more particularly to-the drawing, Figs. 1, 2, I show a window casing at 1-2. The portion 1 of said casing has a track member 3 mounted thereon, as shown, by means of screws 4: which have their heads counter-sunk below the upper surface 5 of said track 3. The track member 3, Fig. 3, has one of its edges turned upwardly at right angles thereto as at 6, thence inwardly a distance as at 7 andthen downwardly as at 8 thus forming a channel 9 having an opening as 10 on the inner side thereof as shown and opposed to and parallel with the track surface. 'At 1111 are orifices passing through track member 3 for purposes hereinafter disclosed.

At 12, Figs. 1, 2, is shown a window supof member 19.

porting plate having orifices 13 passing theiethrough for the purpose of securing sald plate to the underside of a window vsash 14, shown in dotted lines, by means of screws 15 which have their heads countersunk flush with the under surface of plate 12 as shown in Figure 3. The ends of plate 12 have depending portions 16 through which orifices 17 pass, their upper portions being flared as at 18.

I show at 19, F ig. 3, a shoe member having a double thickness as at 20' and a boss formed thereon as at 21 through an orifice 22 passes. The shoe 19, Fig. 4, has a portion 25 extending in a direction opposite to the edge, 26, and has its under surface 27 on the same plane as the under surface 28 of portion 20 The surfaces 27 28 are formed to slide over track 3 and the outer edge 29 of portion 25 is bent upwardly at right angles to the plane of surfaces 27-28 so as to slide freely in the channel 9. The portion 25 passes through the orifice 10 as shown in section in Figure 3. The ends of the upturned portion 29, Fig. 4, maybe bent at right angles thereto to form fingers 30 of a length of lesser proportions than the width of channel 9.. At 31 is shown an arcuate spring member which may be placed between the fingers 30 of portion 29 of member 19. The length and curvature of the same are such as to press the portion 29 against the depending channel wall or portion 8 of track 3, as shown, thus causing sufficient frictional contact between track 3 and the shoe 19 to hold the same and window sash in any position in which it may be placed along the track while at the same time allowing the shoe to be freely moved along said track and the window correspondingly adjusted.

Pivotally mounted upon track '3 at one end thereof is a link 32 held in place by rivet 33 passing through opening 11 in the said track. The outer end of the arm 32 is pivotally mounted upon the under side of plate 12 on depending portion 16 by means of rivet 3 1 passing through orifice 17 in said late. p The length of the track 3 is determined by the length of plate 12 and arm 32 as is shown in Figure 2 which shows the several parts in their respective positions when the window is'closed."

If it is desired to open the window the shoe 19 is slid along on track 3 by pushing on the window sash which causes a. turning movement of plate 12 on shoe 19, and arm 32, due to its length and connections causes the shoe to slide on the track, until the portion 25 strikes the link '32 at a point as shown at 35 in Figure 1. The window is now at right angles to the casing so that the outer surfaceof the same may .be easily cleaned.

The window is prevented from rattling or from movement in either direction, due to air currents, by means of spring 31 which as stated, before, causes a decided frictional contact between the shoe and i the track which holds the window in any position desired. This is more readily accomplished by having the device placed on both the lower and upper rails of the sash which al-v lows the window to be swung open or shut quickly and easily by avoiding the uneven leverage exerted on the mechanism when the window sash is grasped at its edge oppdsite that to which the shoe is attached.

Thus it can be seen that I have provided a device of the character indicatedwhieh will allow a window to be swung open and free from the casing at both sides whereby it may be cleaned on the outside from the interior of the building. The device is smooth and positive in operation and provided with a simple means for securingthe several parts against movement when extended, as well as being easily installed upon any window and being'highly efiicientin'its practical application. i

It is to be understood, of course, that while I have herein. shown and described one particular embodiment of my invention, changes in form, proportion, construction and method of operation may be made with in the scope of the appended claims.

I claim 1. A window support comprising a track, a shoe slidably connected thereto, a plate pivotally mounted on said shoe, a link pivotally connected to said plate and track and an extension carried by said shoe and engageable with the end of the link connected to said track.

2. A window support comprising a track, a shoe having a recess formed therein slidably mounted in said track, a plate pivotally mounted on said shoe, a link pivotally connected to said plate and track, and an outwardly directed arcuate spring member mounted in the said recess in said shoe to slidably engage said track.

3. A window support comprising a track,

a shoe having a recess formed therein slidably mounted in said track, a plate pivotally mounted on said shoe, a link pivotally con- .nected to 'said plate and track, and an arcuate spring member removably mounted in the said recess in saidshoe to slidably engage said track.

4. A wmdow support comprising a track having a surface arranged in opposed relapivotally mounted at a fixed point on said track to swing in a plane parallel to said surface, and a plate pivotally connected to said link and said shoe to swing in a plane parallel to said surface. I

6. A window support comprising a track, a shoe slidably connected thereto, a plate pivotally mounted on said shoe, a link pivot-- ,allyconnected to said plate and track and engageable with said sliding shoe.

7. A window support comprising a track, a shoe slidably connected thereto, a plate pivotally mounted on said shoe, a link pivot-- ally connected to said late and track and said shoe engageable with a stop for limit ing its movement on said track.

8. A window supporting unit comprising a track, a shoe slidably connected thereto, a plate pivotally mounted on said shoe, a link pivotally connected to said plate and track and means for stopping movement of said shoe.

. 9. A window supporting unit comprising a track, a shoe slidably connected thereto.

a plate pivotally mounted on said shoe, and.

adapted for engagement with the sash of a swinging window, and a link pivotally connected to said plate and track.

10. A window supporting unit comprising a track, a shoe slidably connected thereto, said shoe being adapted for resilient and slidable engagement with said track, a plate pivotally mounted on said shoe and a link pivotally connected to said plate and track.
